MILITARY INTELLIGENCE SERVICE, WAR DEPARTMENT, Washington DC, SPECIAL SERIES No. 15 German Coastal Defenses, June 15, 1943
"Germany is at present committed to a strategic defensive on her Western Front, and in recent months she has had to spur herself to feverish activity to add new fortifications on that front. Despite this recent emphasis on fortifications, however, there is no factual basis for the popular belief that the German High Command is suffering from a "Maginot Complex."
The Germans well understand that fortifications are truly offensive in character when their employment is based on the military maxim of economy of force. They cannot defend adequately at all points, but by the use of permanent fortifications to maintain an effective defense with a minimum of man power, they hope to keep the bulk of their force in reserve for offensive."
